Union City-based design company Themendous has replicated a 7-foot-tall sculpture of Entenmann's red velvet crinkle cut doughnuts in honor of National Doughnut Day.

The sculpture, which will be unveiled tomorrow at 23rd Street between Broadway and Madison Avenue in Madison Square Park in Manhattan, took "four long days" to build out of foam, said Themendous owner Giovanni Calabrese.

"A piece like this would normally take a week" to complete," Calabrese said.Formerly Custom Creations, Themendous has been in business for more than 20 years. The design company has worked on pieces for "The Sopranos" and Google's headquarters, along with producing a number of pieces for the Macy's Day Parade, Calabrese said.

"Macy's used to use fiberglass," he said. "Now they have their own foam department."

It was Calabrese's suggestion for the retailer to switch over to the material he is most partial to; it's used almost exclusively in the sculptures.

Although Themendous' reach expands across the country, the designers have worked on local pieces in Hoboken restaurants and the Weehawken Public Library, where they created a giant talking tree and puppet stage.

The average cost of a piece ranges from $500 and up, with some costing $200,000, said Calabrese.

National Doughnut Day was created by the Salvation Army in 1938 to raise money for needy people and has been observed every year since on the first Friday in June.

Calabrese will be on hand in Manhattan at tomorrow's unveiling. There will also be free doughnuts.
